A currently unreleased iMac running on what appears to be an Apple Silicon chip has leaked through a report file in Xcode's Crash Reporter feature. As Apple shifts its Mac lineup over to first-party chips, reports and rumors indicate that one of the next devices in line will be the iMac. Apple is reportedly working on two all-in-one Macs with ARM processors to replace the 21.5-inch iMac and the 27-inch iMac. Amid those rumors, an iMac device with an ARM chip has surfaced through the Xcode Crash Reporter feature. 9to5Mac by DraftCloud developer Dennis Oberhoff, indicates that the app crashed while running on an iMac with an ARM processor. Apple doesn't currently sell an all-in-one with an Apple Silicon chip, so the file surfaced from an unreleased model.
